ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

DOE extends Centrus’s HALEU production contract by one year
Centrus Energy has announced that it has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF6. According to Centrus, the extension is valued at about $110 million through June 30, 2026.

The diagnostics are critical systems for the operation and research program of ITER, as they are used to protect the components, to control the plasma discharge, to understand the behaviour of the plasma and to measure its performance. Representing more than 50 subsystems, they add an extra level of complexity and technical challenge to the project. In order to ensure that the overall ITER machine will be able to reach its ambitious availability objective, a Reliability, Availability, Maintainability and Inspectability (RAMI) approach has been defined and applied to the diagnostics as well as all the other ITER core systems.The purpose of this study is to estimate the inherent availability of the measurements groups used for machine protection and basic control in order to ensure that the ITER machine reaches its inherent availability objectives.
